BLOWPlPE.

SPECIFICATION forming part of Letters Patent N 0. 594,922, datedDecember 7, 1897.

Application filed March 12, 1897. Serial No. 627,174. (N 0 model.)

To all whom it may concern.-

Be it known that I, CHARLES ALFRED WEB- STER, a citizen of the UnitedStates, residing at Independence, in the county of Buchanan and State ofIowa, have invented certain new and useful Improvements in Blowpipes, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to improvements in blowpipes in which a lamp orfeeder is used to supply the gases, which are directed in a jet orflame, for use especially by jewelers and dentists, although it may beused in any case or for any purpose where it would operate effectively.

The object of my invention is the provision of a device of thischaracter which will direct a flame of any desired size, which can bereadily accommodated to the work, which is clean and will not soilthe'hands orclothing of the user, and which is simple, inexpensive, andpractical.

To attain the desired objects, the invention consists of a blowpipeembodying novel features of construction and combination of parts,substantially as disclosed herein.

Figure 1 represents a side elevation of my device complete, and Fig. 2represents a vertical central sectional view thereof.

In the drawings, A designates the lamp or reservoir for containinggasolene or other liquid from which an inflammable gas can be produced,provided with a cap B, to which leads the blowpipe C, and also passingthrough the cap and down into the reservoir is the pipe or tube D. Thepipe or tube D leads to the metal hand-pipe E, with which communicatesthe horizontally-disposed pipe F, passing through which is the stem orrod G, to one end of which is connected the jam-nut H, which operatesagainst the washer J to secure the disk K, carried by the other end ofthe rod, and bring any one of the openings L in said disk opposite theoutlet or discharge opening M of the disk N, which closes the end of thetube or pipe. It will be noted that the outer disk has a series ofopenings of varying sizes, any one of which may be brought in line withthe openings in the stationary disk to cause a jet of any desired sizeto be diinlet of the flame-pipe is a netting Q, and in the mouth of theflame-pipe, adjacent to the netting, is a plug of porous material, suchas raw cotton, like R.

From the foregoing description, taken in connection with the drawings,the operation of my blowpipe will be readily understood, but, brieflystated, is as follows: ,Air is forced into the tank or reservoir throughthe blowpipe, making a gas, which is then forced upward through the tubeand hand-pipe and outward through the horizontally-disposed pipe and theflame-pipe, and when such gas is ignited the flame may be directed inany size upon the object which is being operated upon, as will bereadily understood by all conversant with such matters.

In a blowpipe the combination of the vaporconducting pipe,the pipecommunicating with the upper end of the vapor-pipe, having one endclosed and the other end provided with a cap having a single opening,and a stem or rod passing through said pipe carrying at one end ajam-nut and at the other end a disk provided with a series of openingsto register with the opening of the pipe and a flame-pipe having itsfree end adjacent to the openings of thedisk.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES ALFRED WEBSTER. Witnesses:
